Nazi Party, political party of the mass movement known as National Socialism. Under the leadership of Adolf Hitler, the party came to power in Germany in 1933 and governed by totalitarian methods until 1945. Anti-Semitism was fundamental to the party’s ideology and led to the Holocaust, the systematic, state-sponsored killing of six million Jews and millions of others.

When unemployment began to drop in Germany in late 1932, the Nazi Party’s vote also dropped, to about 12,000,000 (33 percent of the vote) in the November 1932 elections. Nevertheless, Hitler’s shrewd maneuvering behind the scenes prompted the president of the German republic, Paul von Hindenburg, to name him chancellor on January 30, 1933. Hitler used the powers of his office to solidify the Nazis’ position in the government during the following months. The elections of March 5, 1933—precipitated by the burning of the Reichstag building only days earlier—gave the Nazi Party 44 percent of the votes, and further unscrupulous tactics on Hitler’s part turned the voting balance in the Reichstag in the Nazis’ favour. On March 23, 1933, the Reichstag passed the Enabling Act, which “enabled” Hitler’s government to issue decrees independently of the Reichstag and the presidency; Hitler in effect assumed dictatorial powers.
